SAV-EIG ATTACHMENT FOR TRACTORS.

Application filed November 22, 1923. Serial No. 676,360.

operative or an inoperative position anc` when in the latter position is adapted to be left upon the tractor while the tractor `is moved from point to point.

Further objects are to provide a saw rig attachment for tractors which is so organized that it may be readily driven from the standard driving' pulley or take-ott wheel of the trac-tor', which is provided with a recip-V rocable table adapted to hold the wood to be sawed, which is provided with a sollt aligning saw guide, and with n'ieans to guard against accidental Contact of the wood with the saw, and which is provided with a tem porary retaining means for holding the worl table away from the saw. y

An embodiment of the invention is shown in the accompanying' drawings, in which Figure 1 is a side elevation of the device showing it in operative position on the tractor.

Figure 2 is a front elevation of the device.

Figure 3 is a plan view of the structure shown in Figure 1.

Figure 4 is a detail illustrating the temporary latching or locking means. y

Figure 5V is a further detail showing the means for clamping the device to the front portion or radiator oi: the tractor.

rlfhe device comprisesy a frame 'formed of vertical side angle irons v1 which are connected by upper and lower transverse members 2 and 3 which may alsoj if desired. be ot relatively7 smaller angle irons. This traine, as shown in Figure 1. is adapted to lit over the front of the radiator 4 of the tractor with the side flanges ot the angle irons 1 lfitting over the sidesoic the radiator, as shown. A U-shaped strap member `5 has its arms pivotally joined, as indicated at o to the angle irons 1, and is adapted to tit over the filling neck 7 of the radiator,l as shown in Figure 1, to thus support the device. A transverse channel iron 8 extends across the front ofthe frame and joins the angle irons 1.

This channel iron carries rearwardly projecting bolts 9 which carry lugs 10, such lugs being adiustably held vin position b v means of: winglr nuts 11.

. Itis to be noted that the lugs 10, as may be seen from Figure .5, are provided with ears 12 adaptedv to engage the rear face or the radiator 4 to thus clamp the frame rigidly in position upon the radiator.

The transvcrse'channel iron 8 carries a pair of lugs 13 to which are pivoted outwardly projecting channel irons 14. These channel irons are each provided with a pivotally lioined angle iron or brace 15 which is adapted to extend downwardly from an intermediate portion of each of the channel irons 14 to the front axle 16. It is tobe noted from Figure 1 that the members 15 are provided with ripper and lower arms 1'? and 18 which are anertured and adapted to receive a pin 19. These pins are adapted to be 'slipped into position when the parts are as shown in Figure 1 and to thus temporarily lock the members 15 to the front axle and to prevent inadvertent disconnection of suchmembers from the axle.

A pair of bearings Q0 are secured to the outwardly projecting channel irons 14 and carry the shaft 21. One end ofA this shaft is provided w-ith'a driven pulley '22' adapted to be belted to the usual driving pulley of the tractor. such pulley being commonly known as the power take-oli' pulleyv oit the tractor. 'The other end of the shaft is provided with ay circular saw 23 which is located exteriorly of the outwardly projecting channel irons 14. y Q

A workplate 24 is supported by means of a plurality of flanged wheelsZ which are suitably journaled in appropriate members 2G carried by the lower side of the workplate. These tianged rollers tit within the inwardly turned channels formed by the channel irons 14, as may be seen from Fig-y ure 2, and thus both guide and support the workplate. The workplate 24 is provided with a forward stop 27 which contacts with one of the bearings .20-to thus limit the forward motion of .such workplate.` Rearward motion of the workplate is limit-ed by means of a stop or plug 28 (see Figure 3) carried by one of the channel irons` 14. It is desirablekat times to lock the workplate in its mitermost position. This is readily accomplished by providingl a leait spring 2S) which is bolt-ed to the inneiI face ot one ot the channel members and is provided with a slanting cam or lug,` 30 provided with an abrupt shoulder adapted to engage the projecting portion 8l (see Figure 3) ot one ot the axles ot the rollers 25. This spring` 29 is provided with a pin loosely passing' through an. aperture 34 formed in the channel iron lll in order to aid in correct-ly positioning the spring. It is provided with an outer projecting portion adapted to be engaged by a portion oit the body ot the workman when'it is desired to release the wor-k table 2li. This worlr table is provided with a portion which projects beyond the. lett hand channelV iron A, as shown in Figure 3, and an auxiliary support or guideway which is provided for carrying this projecting portion, may be seen :trom Figures 3 and 2 The projecting` portion ot the workplate is provided with a slot 36 therethrough and has bolted to the under side thereof a wooden bloclr 37. upor` the workplatc in its initial integrity and, thereatt'r, the workplate is slid towards the saw thus allowing' the saw to cnt its kert through the block 37 thus insuring` proper aligninget the guiding slot and the saw tor subsequent work.

It is desirable to provide a guard tor the saw to prevent contact ot the wood with the saw when the workplatc 2d is in outermost position. This is readily secured by providing an upstanding` U-shaped guard 38 (see Figures 2 and which, when the workplate is retracted, prevents the wood trom inadvertently engaging' the saw.

A convenient way ot supporting the auxiliary support or guides 35 is by means ot a pair oit enfile irons 39 which are bolted to the under side ot such guide and to the under side'ot the channel irons l-i, as may be seen trom Figures l and 3.

lthe pins 19 are withdrawn thus :treeing the brace members l5 and permitting-the torward traine tornied oi?V the channel irons 14e to be swung` ujiwardly about their pivotal union with the lugs l-. l."Vlirn ythe device mvnngg; upwardly, the shaft is engaged by a. paw] l0 pivoted to one ol the uprielits or channel irons l, as may be seen troni Figure and thus the device may be held in its elevated position and the tractor may be readily driven to the de` ire/d point. A

lt will thu; that in etieot a portable saw inill has been provided which may be moved from point to point, wlreh may be readily adjusted to operative position, and which may be readily moved into inoperative position and locked iu such. position.

This wooden block is positioned llt wil further be seen 'that a sawrig tor a tractor has been provided which maybe readily 'fastened in a very rigid and secure n'ianner to a nidard torni ot tractor without requiring any tools whatsoever. v n

Although the invention has been described in'considerable detail, it to be understood that the invention may be variously einbodied and is,ftheretore, to be limited only as claimed.

le claim:

l. A. saw rip; tor detachable engagement.
